Exodus 32:15-19

15Moses turned and went down from the mountain with the two tablets of the testimony in his hands. The tablets were written on both sides – they were written on the front and on the back.

16Now the tablets were the work of God, and the writing was the writing of God, engraved on the tablets.

17When Joshua heard the noise of the people as they shouted, he said to Moses, “It is the sound of war in the camp!”

18Moses said, “It is not the sound of those who shout for victory, nor is it the sound of those who cry because they are overcome, but the sound of singing I hear.”

19When he approached the camp and saw the calf and the dancing, Moses became extremely angry. He threw the tablets from his hands and broke them to pieces at the bottom of the mountain.
